The exciting Big Heart Series continues when Alfred Swallow meets a wild roan stallion. Not just any stallion, but a medicine hat roan stallion that is believed to have special powers.

The bond between Alfred and the stallion reaches far into a world of hopes and dreams. It's 1929 and times are hard for Alfred's Lakota family on the Dakota prairie.

But time is short, as the race is just weeks away. Unaware of the dangers that lie ahead, Alfred prepares to train the horse. Even though the odds are against Alfred and his team, something in the grandstand catches his eye on the day of the race, and that changes everything. Can Alfred's determination and prayers carry them through to win?
